boto3 error for creating stack instances with "deployment targets" – Amazon web services

I’m using service managed permission to create_stack_instances for an OU, filtered by intersection of a list of accounts and when i run the command, it gives me an error, Can someone please tell me what’s wrong with my code here?

1. error via cli

   Parameter validation failed:
   Unknown parameter in DeploymentTargets: "AccountFilterType", must be one of: Accounts, AccountsUrl, OrganizationalUnitIds

2. error via lambda

   [ERROR] ParamValidationError: Parameter validation failed:
   Unknown parameter in DeploymentTargets: "AccountFilterType", must be one of: Accounts, AccountsUrl, OrganizationalUnitIds

3. lambda code:

   def add_stack_to_stackset(StackSetName, accountid):

    response = CF.create_stack_instances(
        StackSetName=StackSetName,
        DeploymentTargets={
            'OrganizationalUnitIds': ['ou-blah'],
             'Accounts': [accountid],
            'AccountFilterType': 'INTERSECTION'
        },
        Regions=['us-east-1']
    )
    op_id = response['OperationId']
    return op_id
   

4. cli code

   aws cloudformation create-stack-instances –stack-set-name demo –deployment-targets OrganizationalUnitIds=ou-blah,Accounts=12345,AccountFilterType=INTERSECTION –regions us-east-1
